There's a thing called "morals" which prevents many people from illegally distributing books. Very much a "personal reason".

Those of us that don't upload their media are not part of the problem. The problem of illegal distribution is created by people who have no problems with that. I'm trying to find a way to ensure that they (together with publishers) stop making life miserable for honest media users (or force them to do prohibited and/or illegal practices like DRM-stripping).
